Naddika [18.5K]

1748 people are expected to stop at the gift shop out of 2300.

Step-by-step explanation:

Given,

Number of random sampled people = 350

Number of people who stopped at shop = 266

Percentage = \frac{People\ stopped}{Total\ people}*100

Percentage = \frac{266}{350}*100=76\%

Therefore,

76% people would stop at the gift stop.

Number of people = 2300

Expected number = 76% of total

Expected number = \frac{76}{100}*2300

Expected number = 1748

1748 people are expected to stop at the gift shop out of 2300.

It takes Dwight 1 1/3 hours to run the sunshine trail. Mike 3 1/5 hours to walk the same trail. How many times as long does it t
Anit [1.1K]

For this case we convert the mixed numbers to fractions:

Dwight:1 \frac {1} {3} = \frac {3 * 1 + 1} {3} = \frac {4} {3} = 1.33

Mike:3 \frac {1} {5} = \frac {5 * 3 + 1} {5} = \frac {16} {5} = 3.2

It is observed, that in fact, Mike takes more time to travel the road.

We subtract to know how much more time it takes Mike:

\frac {16} {5} - \frac {4} {3} = \frac {48-20} {15} = \frac {28} {15}

So, Mike takes \frac {28} {15} hours more than Dwight to walk the road.

Answer:

Mike takes\frac {28} {15}hours longer than Dwight to walk the road.

True [87]

Step-by-step explanation:

Surface area is pretty synonymous with area.

Paint is measured in volume, so not surface area

Since its just the walls its not total surface area, but surface area of the walls.

How much water will it take to fill a rectangular container?

water is measured in volume, especially when wanting to fill something.

How much topsoil can a gardener place in his wheelbarrow?

Wants to know how much topsoil is needed to FILL the wheelbarrow, filling is volume.  So not surface area.

How much fabric is needed to make a pillowcase for a pillow?

Not asking to fill the pillowcase, just how much is needed for the thin, one layer thick case.  So this is surface area.
